Michael Kremer, the 2019 Nobel prize winner presented the O-ring theory in 1993, suggesting that tasks of production must be executed proficiently together, and that people with similar (high) skill levels should work together.
This model helps explain Human capital flight and international economic disparity. As Kremer puts it, "If strategic complementary is sufficiently strong, micro-economically identical nations or groups within nations could settle into equilibrium with different levels of human capital"
I think not. In a country as Colombia, had been applied such models, such as Solow, Lewis, Rostow but it remains underdeveloped. ¿Why not to think in coordination failures?
Education and science development could enhance skills of people, so it become so easy to match the workers skills.
